CENTRIFUGAL CREAM-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 414,644, dated November5, 1889.

Application filed September 6, 1838. Serial No. 284,769. (No model.)

To (all whom, it may concern-.-

Be it known that I, SVEN J ('iNSSON, a subject of the King of Denmark,residing at C0- penhagen, in the Kingdom of Denmark, have inventedcertain new and useful Improvements in Centrifugal Cream-SeparatorsCapable of being Regulated while in Motion, of which the following is aspecification.

The invention relates to a centrifugal cream-separating machine arrangedso that the outflow of cream can be regulated during the working of theseparator, whereby the useful eifect of the separator becomes a maximum.

On the annexed sheet of drawings, Figure 1 shows the improved separatorin vertical section. Fig. 2 is a plan of the same. Fig. 3 is a verticalsection, on a larger scale, of the upper portion of the separator. Fig.4 shows a horizontal section through the drum and skim-milk pipes h.

The improved centrifugal separator is sup ported upon a standard A, inthe lower part of which is situated a shaft B, with beltpu1- ley C, towhich power is transmitted from any convenient source.

Upon the end of the shaft B there rests the shaftD of the centrifugalseparator, which is forced to assume the rotary movement by means of ahorizontal pin on the one shaft The shaft of the separator rests in abearing E, which is rendered yielding by means of an inserted rubberring E, and which is lubricated by a pipe f from an oil-vessel F. Theshaft at its upper end carries a disk to which is riveted thecylindrical drum G. Contrary to the usualpractice in constructingcream-separators, this drum is made of small diameter, whereby themanufacture of the same is facilitated and a better product is obtainedfrom the machine. There is aldo the great advantage that the creamleaves the separator without froth, as the milk practically fills thewhole space of the separator-drum, so that there is almost no air in thesame. Moreover, by this means there is only the slightest possibleresistance of the air against the outer wall of the cylinder duringrotation, and consequently the smallest possii'ile consumption of powerin proportion to useful work.

The drum is provided internal] y with a tube G and with three vanes orwings G, which at their free edge are held by means of a projectionfixed to the wall of the drum and a hook g riveted to the vane, so thatthe tube, together with the vanes, can be readily disconnected and takenout. By this means the separator can be easily cleaned, as it is quitesmooth inside when the inner fillingpipe and the vanes have beenremoved.

The drum G is closed at its top by the screw-cut cover H, which, whenthe machine has to be cleaned, can be screwed off, whereby'the drum canbe divided into two parts G and H. In this cover are inserted twoparallel outlet-pipes 71- for the skinbmilk. These pipes, which areplaced, as shown in Figs. 1,

2, 3, and 4, at the sides of the tube G, lead from inside the wall ofthe cover H across the broad part of the drum and through the wall tothe receiving-vessel g.

The cover H is provided at the top with a central opening in which isaffixed a pipe 1, (provided with a flange l,) which pipe 6X- 7 5 tendsabove the upper end of the pipe G. The improved separator is thus quiteclosed, in contradistinction to other constructions heretofore employed.

Two or more vertical holes r' are formed in the flange I.

Around the pipe I is placed another pipe .K, which is provided with anupper flange 7t and a lower flange 7t. As many conical pegs 7c" arescrewed into the lower flange k as 8 5 there are holes 11 in the flange1', each peg corresponding to its hole. A spiral spring L, which isinserted between the pipes I and K, has a constant tendency to raise thelatter. This tendency is counteracted by a nut M, which presses againsttheupper flange 7c and is screwed into a proj ecting-arm N, carried bythe standard and surrounds the pipe K. The nut M, Figs. 1 and 8, isprovided at the top with a fluted flange 1.", against which bears arough spring 0, so that the nut is prevented from rotating with thetube. The milk which is to be centrifugally treated is led from acontaining-vessel P to the drum G through the pipe G. After treatment inthe separoe .rator the milk passes out through the pipes 72', extendingthrough the cover ll, and is collected in a receiving-vessel g, whenceit flows through the pipe g. The separated cream passes out through theopenings '6 under the flange it into the receiving-vessel S, which isprovided with the outlet-pipe S. The quantity of the out-flowing creamcan be regulated, even during the operation of the machine, by screwingthe nut M, whereby the conical pegs 70 on the flange 7c are raised outof the holes 11 or are depressed to a greater depth in the sa1ne,'sothat the passage is widened or contracted. Of course the separator maybe arranged in such a manner that the discharge is effected below,instead of at the top, as shown.

The centrifugal machine described above, which intends the separation ofcream from milk, differs in all essential points from the centrifugalmachine for which I have applied for Letters Patent by applicationSerial No. 280,234, filed July 17, 1888, only a part of the arrangementfor the milk-inlet and the regulation of same being identical in bothapplications, and such part is not claimed in this application.

Having thus described my invention, I claim-- 1. In a centrifugalcream-separator, the combination of the arm N, carrying spring 0 and thenut M, having a roughened flange, with the casing K, provided withconical pegs 7c", the spring L, the revolving drum, and the flange I,having holes 71, substantially as set forth.

2. In a centrifugal cream-separator, the combination of the drum G, thecover H, secured thereto, the supply-pipe G, the vanes G, pipes h,flange I, having holes 1, casing K, provided with regulating-pegs k, andmeans for operating said casing, substantially as set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
